To @ZZ whom t may] concer/1t Be it known that l, GEORGE MnLLon, a citizen of United States, residing at 1947 N. 19th St., Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful improvements in Spark-Plug Cleaners, of which the following is a specification.

The invention relates to spark plugs, and more particularly to cleaning devices therefor, and has for an object to provide a simple device that can be cheaply manufactured, and which is adapted to effectively clean spark plugs, and more particularly the contact points thereof, for the purpose of removing any carbon or other deposits which ordinarily tend to incrust or deposit themselves upon the contact points, and thus 'destroy the efficiency of the spark plug.

Among other features, the invention comprehends a simple device which consists of few parts, and in fact the body of which is formed of a single piece of material that can be crushed or bent to form a holder for suitable brushes, and also carry scraping elements, so that the spark plug can be subjected to several operations by use of the device to effectively clean the contact points of the plug.

In the further disclosure of the invention, reference is to be had to the accompanying drawing, constituting a part of this speer ication, in which similar characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a plan view of the spark plug cleaner.

Fig. 2 is a fragmentary horizontal sectional view taken through the spark plug cleaner, showing details of construction.

Fig. 3 is a transverse sectional view through they scraping and cleaning part of the cleaner, and e Fig. 4 is a perspective View of the blank from which the body of the spark plug cleaner can be made.

Referring more particularly to the views, and especially to Figs. 1, 2 and 4C, l employ a cylinder 10 of metal that can be readily bent or crushed Without breaking or cracking, said cylinder to constitute the body 11 of the cleaner. rl`he end 12 of the body has a wire brush 13 secured therein, and the end 12 is then crushed down upon the inner ends of the wire strands of the brush, thus holding the strands forming the brush firmly together, andv in rigid `engagement with the interior of theL body. rlhe other end 141 of the body is similarly treated by securing thereto a bristle brush 15, the .inner portion of the brush being secured in the body andthe body then crushed down, as shown at 14:, rigidly securing the bristle brush in position, it being particularly noted, however, that the bristle brush lies at right angles to the wire brush 13. portion of the body now receives a quantity of line piano or other wire A`16, which is vwound around the cylinder 10, and that portion of the cylinder with the wire 16 around The medial it is then crushed flat, and thus crushing the Wire flat to provide scraping surfaces 17 and, in fact, a scraping portion or element 18, which scraping portion is formed by the crushed wire, and is somewhat in the nature of a filing surface, being rough, due to the texture of the Wire and the crushing of the wire when the body is crushed. The ends of the wire can be secured to the body by suitable pieces of solder, as shown at 19, or in any other convenient manner, and it will be clearly seen by reference -to Fig. 2 that by having the cylinder 10 crushed to form the different parts mentioned hereto fore, the fibers or bristles of the brushes 13 and 15 can not be pushed inwardly any farther, due to the fact that in crushing down the medial portion of the cylinder 10, converging portions 20 will be formed thereby, and these will limit any inward movement of the fibers or bristles of the brushes,

the flatteningV of the ends of the body preventing the removal of the fibers or bristles of the brushes.

lt will clearly be seen that in use, when it is desired to clean a spark plug, the spark plug is removed from the particular piece of machinery with which it'may have been connectedk or associated, and by means of the wire brush thev Contact points of the spark plug can be cleaned ofany deposits of carbon or the like, and if` necessary the contact points can be further cleaned or scraped by subjecting them to the roughened scraping surfaces 17, which 4surfaces may first be inoistened with gasolene so that the scraping action on the contact points will effectively remove lthe deposits, and

result in a clean, smooth ksurface capable ofy electric conductivity. Finally, the bristle gasolene or particles of the material that brush 15 can be employed to dry 0H any has been scraped from the Contact points, and thus it Will be apparent that the device described provides a compact and efeotive tool for the purpose mentioned. 5 I claim:

A spark plugeleaner comprising a longitightly Wound around said flattened portion With the convolutions of the Wire in contact with each other and With the ends of the Wire secured to the body whereby said scraping surfaces Will be rigid and immovable yrelative to said body and held against any longitudinal or transverse movement on the Hattened `portion thereof.

In testimony whereof I aiiiX my signature.

GEORGE MELLOR.
